17 'o all whom t may concern.'

Beitknown that I, HORACE G. Esmnnoon, a citizen of the Dominion of Canada, and a resident of 1West Summerland, in the county of Yale, Province of British Columbia, Canada, have invented certain new and useful Improvements in Doors; and I do hereby declare that the following is a full, clear, and exact description thereof. reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

' This invention relates to improvements in doors and consists of the matters hereinafter described and more particularly pointed out in the appended claim.

The object of the invention is to provide a door which is adapted to be readily and easily changed from a full panel door to a door which will permit the entrance of light and air into the interior of a room without permitting the entrance of flies or other insects. As will be apparent from the following description, the change from one form of door to the other and vice versa may be readily brought about, thus embodying in a single door the utility and benefits which have heretofore required the use of two separate doors for each door opening or casing.

In the drawings: Figure 1 is a view in elevation of the interior side of a door made in accordance with my invention and illustrating the same when used as a full panel door, a part of said door being broken away to more clearly show the interior construction thereof. Fig. 2 is a view in elevation of the weather side of my improved door illustrating the parts thereof in changed relation as when said door is being used to permit the entrance of light and air and the exclusion of insects. Fig. 3 is a fragmentary vertical sectional view through my improved door on an enlarged scale, the plane of the section being taken on a. plane indicated by the line 3 3 of Fig. 1. Figs, 4 and 5 are horizontal detail sectional Views through the door, the planes of said sections being indicated by the lines 4 4 and 5 5 respectively of Fig. 1.

Referring in detail to that embodiment of my invention illustrated in the accompanying drawings 10 indicates my improved door as a whole, which may be made of wood, of metal or of other suitable material. The door constitutes an open frame compris ing the usual upright stiles 11, 11, and top and bottom rails 1Q, 13, respectively, said stiles and rails defining an opening or space 14. The lower part of the space 14 isclosed by spaced panel members 15 and 16, in such manner as to provide aY compartment l-P. The panel member 16 is fixed-and the panel member 15 is removable for the purpose of inspection or repair.

17, 17, indicate upright guide strips attached to the inner edges of the stile 11.l said strips extending the full height of the opening 14. To the opposite faces of the Stiles 11 and of the top rail 12, adjacent to that part of the rectangular opening 14 above the panels 15 and 1G are attached molding strips 19, 19 and Q0, respectively, which overlap that part of the stiles and top rail defining said ope-ning.

The panels 15 and 1G. guide strips 17, molding strips 19 and 20, provide channels or ways in the plane of the said stiles and rails in which are slidably mounted panel frames 21, 22, respectively. The combined thickness of the said frames approximates the thickness of the stiles and rail and the upright members of said frame are rabbeted at their lateral adjacent margins so as to overlap the guide strips 17. (See Figs. 3, 4 and 5). As is illustrated herein the frame 21 which is arranged adjacent the interior or inside of the door, is adapted to receive an opaque or transparent panel Q3. As shown this panel is made of glass. The frame 22 which is arranged adjacent the weather or outside of the door is adapted to receive a panel Q4 which as illustrated comprises a comparatively fine mesh wire screen.

As is apparent, the said frame 21 and 22 are adapted for independent sliding vertical guiding movement within the confines of the stiles and rails defining the opening 14. Should it be desired to have the use of a door embodying the characteristics of the ordinary full panel door so as to permit of the entrance of light and to keep out the cold, wind or rain, the frame`21 is moved upwardly in its associated channels or ways until it closes that part of the opening 14 above the panels 15 and 16 before referred to. It may be automatically locked in this position by means of spring pressed plunger locks 21a, 21, there being one of such locks attached to each upright of the panel frame 21 which are operable from the interior side only of the said fra-me, said locks coacting with apertures 21", 21", located in the associate channel. 'Preferably when the frame 21 is in its raised position, the frame 22 (which is provided with locking devices 22a, 22, similar t0 the locking devices 21a before mentioned) is in its lowered position within the compartment 14a before mentioned, but the relative positions of said frame may be reversed. Both of said frames may be in their raised or lowered position at the same time when desired.

As will be apparent from Fig. 3 of the drawings, when the frame 21 is in its raised position, a part of the bottom horizontal member thereof extends a short distance into the compartment 14, and when the frame 22 is in its lower position within the compartment 14, the top edge of the top horizontal member of said frame projects a short distance above the top of the panel 16 where itis provided with a hand hold 22c for use in drawing or raising said frame from the said compartment.` The top horizontal member of the frame 21 is also provided on its inside face with a like hand hold 21d for a similar purpose.

It is apparent from the foregoing description that the adjacent faces of the frame 21, 22, are approximately flush with each other and that they each overlap a part of the upright guide strips 17. This construction is advantageous in that it is impossible for any draft of air to seep through the door along the inner edges of the stiles and bottom edge of the top rail and at the same time, the space between the top edges of the panels 15 and 16 is closed when both panels are either in a raised or lowered position,

or when one panel is in its raised position and the other is in its lowered position.

In order to hold the frame 21 in a raised but not fully closed position, I provide one pressed lockin devices 218L may engage in the usual well- {nown manner.

It is apparent froml the foregoing description that my improved door possesses the advantargles and utility of two ordinary doors. he improved door is cheap to manufacture and is easily operated to produce the changes hereinbefore mentioned, making it especially applicable to dwelling houses, cafs, markets, stables, or to any other place.

While in describing my invention, I have referred to certain details in construction and arrangement of parts, I do not wish to limit myself thereto except as may be pointed out in the appended claim.

I claim as my invention:

A door comprising stiles, and top and bottom rails, panels fixed to said stiles and bottom rails to provide a compartment and an opening thereabove, guide-strips fixed to the inner edges of and extending the full height of said Stiles, molding strips fixed to and overlapped on the opposite faces of said stiles about said opening, said panels, guide strips and molding strips providing channels in the plane of said Stiles, movable frames arranged to slide independently of each other in said channels to close said opening, said movable frames having top and bottom horizontal members which are adapted'to co-act with each other to close the top end of said compartment when both of said frames are fully within or fully withdrawn from said compartment and when one of said frames is in said compartment and the other frame is in a position closing the opening above said compartment.

In testimony that I claim the foregoing as my invention I atiix my signature, in the presence of two witnesses, this 15th day of November, A. D. 1915.
